1. Overview
The CNC lathe can realize X-Z two-axis linkage, equipped with Guangzhou CNC system, and has all the functions of NC machine tools, such as linear interpolation, arc interpolation, thread cutting, tool compensation, macro program, error compensation, constant linear speed, program storage and so on.
The machine tool adopts integral casting with good overall rigidity, good dynamic performance, accurate motion precision control, stable machining precision and good consistency, and can be continuously controlled by two coordinates (longitudinal Z, transverse X). It can automatically complete the machining of inner and outer circular surface, conical surface, arc surface, end face and other rotary surfaces, as well as turning thread and other functions. The machine tool is suitable for the processing of accumulators, CNG gas cylinders and the mouth of industrial gas cylinders. It is a special CNC machine tool with good performance-to-price ratio.
2. Applied application
A. The machine is suitable for the processing of cylinder mouth, outer circle, inner hole, car sealing table, internal and external thread and so on, all of which are realized by NC programming, and the single station feeding and discharging device is adopted to realize (semi-automatic / manual 2 states optional). The clamping of the workpiece adopts the arc contact positioning between the front top bowl and the gas cylinder, and the rear positioning adopts the axial compression of the oil cylinder to clamp the workpiece between the two top bowls.
1) Cylinder diameter range: 232-406mm
2) Cylinder length range: 895-1800mm (round bottom)
3) Max. Cylinder weight: 500KG
4) Processing time: 90-120 s/pc (based on PZ27.8 thread, without hole digging time)
5) Thread quality and thread processing capability:
Thread processing shall not have defects such as missing teeth, cusps, flat teeth, double lines of teeth, and so on.
Thread roughness must be above Ra3.2 level
